I have a 6hp Johnson, that I'm having trouble with. I bought it last August, and ran it only a little before winter. I probably put 10 minutes on it in October. It seemed to run fine. I went to start it the other day, and the plugs were fouled, so I got some new ones. I took the air filter off, and squirted some carb cleaner in, pulled the cord. It started and then promptly died. I tried it again and again, same effect. Sqirt carb cleaner in, pull, start, run for 5 seconds, die. I think that no fuel is getting to it, so my hunch is to replace the fuel pump. Does that sound like a reasonable approach? Is there anything else I should try to help diagnose it?
